What Is the Difference Between PHP and JavaScript?


A programming language is a notation of symbolic expressions used to design and describe computations. Programming languages differ according to their level of abstraction. Low-level languages, such as machine code, assembly language, and C, use simple sequences of bits to represent memory concepts directly. Higher-level languages, like Python, JavaScript, and PHP, are more potent. They solve problems using straightforward instructions that map more closely to natural expressions.

The Difference Between PHP and JavaScript

It’s not easy to compare PHP and JavaScript, as they each have completely different functions for web development. First, let’s look at their characteristics.

What Is JavaScript?

JavaScript is a lightweight client-side scripting language that typically executes within browsers to create dynamic and interactive web pages. Users find JS crucial for developing creative, user-friendly websites and mobile apps, game development, PDF forms, and more. The code doesn’t need recompiling, making it faster and more efficient. Advanced server-side JavaScript versions like Express.js, AngularJS, and NodeJS permit developers to build more functionalities into websites.

What Is PHP?

PHP stands for PHP: Hypertext Preprocessor, which means it can create pre-written web pages based on your coding skills and what it does with variables. As a programming language, it follows the very basics of standard syntax, making it easy to learn and use. It’s a vital web technology that enables developers to create graphical user interfaces (GUIs) and manage dynamic web pages.

PHP’s unique functions and features allow it to create high-level interactive web pages like image galleries, login pages, etc. PHP is the most popular open-source server-side script today and runs on most operating systems. It is used in content management systems (CMSes) like Drupal, WordPress, Joomla!, and database servers like SQL, PostgreSQL, Sybase, and MariaDB.

PHP vs. JavaScript

The main differences between these two languages are:

PHP is a server-side scripting language, whereas JavaScript operates on the client. In truth, you need to use the functions of both these languages together to create dynamic web pages and websites. The analogy would be: if PHP is a paintbrush to color a picture, then JavaScript is the paint.

  •  PHP script doesn’t execute within the browser, whereas JavaScript does.
  •  PHP supports databases and CMSes, whereas JavaScript doesn’t back either.
  •  PHP code accepts upper and lower case variables, while JavaScript only agrees with small letters.
  •  PHP doesn’t support the interchange between objects and arrays, whereas JavaScript does.
  •  PHP is a general-purpose language used for creating custom web content, while JavaScript is best suited for building interactive pages and network-specific applications.

Final Take

In web development, PHP and JavaScript are essential in creating dynamic applications and web pages. While JavaScript caters primarily to the front-end, it needs a dynamic backend to work. With over 80% of all websites using PHP in some way, PHP developers and engineers have become an indispensable part of the tech workforce.
